Usure (mécanique)Index. décimale : 668.4 Plastiques, vinyles Résumé : The present work describes the processing and studies the erosion wear characteristics of bamboo fiber reinforced epoxy composites filled with SiC particulate. The mechanical properties of these composites are evaluated and are then compared with those of a similar set of SiC filled glass-epoxy composites. The solid particle erosion characteristics of the bamboo-epoxy composites have also been studied and the experimental results are compared with the reported erosion test results on glass-epoxy composites under similar test conditions by Biswas and Satapathy (2009). The influence of particulate filler on the erosion wear response of composites has been critically analyzed using Taguchi experimental design. This systematic experimentation has led to determination of significant process parameters and material variables that predominantly influence the wear rate of the particulate filled glass-epoxy and bamboo-epoxy composites. The comparative study indicates that although the bamboo based composites exhibit relatively inferior mechanical properties, their erosion wear performance is better than that of the glass-epoxy composites.

Poids moléculairesIndex. décimale : 668.4 Plastiques, vinyles Résumé : Additives play a pivotal role in the processing of polyvinyl chloride (PVC) and various other plastics, enhancing processing efficiency while safeguarding the integrity of polymers. Lubricants are a prime illustration of this principle. Nonetheless, the choice of the suitable additive necessitates meticulous alignment with the specific polymer in question. In this regard, the Hildebrand solubility parameter emerges as a valuable tool. For the first time, we now have access to values for this parameter for numerous widely used lubricants.

Tribologie (technologie)Index. décimale : 668.4 Plastiques, vinyles Résumé : Particularly in sensitive production environments, self-lubricating high-performance plastics offer advantages over greases and oils. Because these materials are relatively expensive, a 2-phase lubricant system consisting of a POM core with a highly-filled PTFE surface layer seems practical. The first part of this study focuses on the mechanisms of action and the saving potentials of such a system. Note de contenu : - Material selection and compatibility
- Various frictional phases
- Structural analysis and possible failure mechanisms
- Lubricant particle distribution
- 2-phase cube model describes mixed structure
- FIGURES : 1. With an increasing content of solid lubricant, the mechanical properties of slide-modified (PTFE) POM products are reduced. The values were determined with an injection molded rod in a tensile test according to DIN EN ISO 527 -2. An initial wear is required to enable a self-lubricating layer to be formed. This is shown by the three-stage progression of the friction coefficient of POM with a 20% PTFE filing versus PE-UHMW (v=0.33m/s, p=0.22N/mm2) - 3. The scanning electron microscope image of PTFE microparticles in a POM matrix shows that the additive particles are not chemically bonded with the plastic matrix, but are located on top - 4. Structural analysis of flow conditions and shear speeds in the mold. The dimensions were determined on specific samples. The layer thicknesses depend on flow and cooling conditions, and can vary, depending on manufacturer parameters - 5. The 2-phase lubricant system is intended to form and anti-friction coating betweenbase and sliding body - 6. The surface layer - as highly filled with PTFE as possible - is of primary importance for slide modification. The 2-phase cube model according to Faust/clauss was developed to obtain the best possible compromise between mechanical and tribological propertiesEn ligne : https://drive.google.com/file/d/1t4lPjjzhSfu2QlGgUkQdQp4iw-qbdfzW/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=29541

Matières plastiques -- Moulage par injection -- Appareils et matérielIndex. décimale : 668.4 Plastiques, vinyles Résumé : In 1991, the management consultant Roland Berger recommended selling off what had formerly been the biggest brush manufacturer in the GDR for one Deutschmark, or shutting it down completely. The owner, which was organized as a cooperative, had different plans. It retooled the Saxon plastics processor as a high-tech company – and is now reaping rich rewards.
